Senior🎓
Top SchoolChristian S is a Principal Software Engineer with 11 years of experience, currently leading platform engineering and delivery excellence at Commerzbank’s Digital Technology Centre in Sofia. He blends hands-on front-end and DevOps expertise—especially React, CI/CD, Terraform and monitoring—with a strong focus on reducing team toil through automation and process improvement. Known for high standards and mentoring, he drives SDLC hygiene, peer reviews and developer onboarding while advocating pragmatic Agile and XP practices. His background includes rebuilding data-visualization front-ends, leading DevOps transformations, and creating pattern libraries and design systems for large clients. A pragmatic idealist, he routinely points out and fixes “the way we’ve always done it,” and candidly admits to having over-engineered and learned from the failures along the way. He pairs a BA in Communication Science with a practical, people-first approach to making software and teams better.
